摘要
介绍一种采用倒π形馈源的新型超宽带宽缝印刷天线,由共面波导(CPW)馈电。对该天线的性能进行了仿真和试验研究,给出回波损失曲线和辐射方向图。试验结果表明,该天线具有约120%的阻抗带宽(S_(11)≤-10 dB),覆盖了3.0～12.0 GHz频率范围。与文献报道的几种同类天线比较,其尺寸是最小的。
A new ultra-wideband wide-slot printed antenna with an inverted π-shaped feed is introduced, which is fed by a coplanar wavegnide （CPW）. The characteristics of the proposed antenna are investigated both numerically and experimentally, then the return loss curve and radiation patterns of the antenna are presented. The experimental results show that the antenna has an impedance bandwidth of approximately 120% （S11≤- 10 dB）, covering 3.0 - 12.0 GHz frequency range. Compared with some reported antennas of the same-type, it is noted that the size of the proposed antenna is the smallest among them.
